514 Notices of Memoirs — Fossiliferous Deposits. 



them, Garex inciirva, is a sea-coast sedge not now ranging south of 

 Holy Isle. 



"A striking peculiarity of the deposit is the abundant remains of 

 the estuarine sedge, Scirpus maritimus, a plant which, growing out 

 of a few inches of water, tends to form a thick belt through which 

 few drifted seeds would find their way. In view of the abundance 

 of this sedge in the bed now examined and of the like-growing reed, 

 Phragmites communis, in the deposit which I searched some years 

 ago, the small number of other plants yet detected is not surprising. 

 Land plants are only represented by two fruits of Lapsana, perhaps- 

 brought by birds. These fruits of Lapsana, as well as those of the 

 sea-aster, are considerably smaller than my recent specimens, but 

 I have not yet had an opportunity of comparing them with fruits of 

 the same species near their northern limit." 



From the fresh- water shell-bed associated with the peat, Mr. E. T. 

 Newton has determined Planorbis spirorbis, Bithynia tentaculata, with 

 probably Candona (an Entomostracan). 



Great Limber Section. 



A boring was also put down under the supervision of Mr. G. W. B. 

 Macturk, who kindly undertook to aid the Committee in this manner, 

 at the Great Limber brickyard, three miles south-east of Kirraington, 

 where there is a further development of warp and sand, believed 

 by Mr. C. Reid to be of the same age as the Kirmington deposit, 

 though no fossils have been found in it. The section seen in the^ 

 brickyard and proved in the boring was as follows : — 



Surface soil and clay with stones (at 110 feet above O.D.) 



Loamy sand contorted and mixed with warp 



Laminated blue warp with sandy streaks ... 



Pan 



Cui-rent-bedded sand 



Sharp sand 



Flint, sand, and rounded chalk pebbles 



Solid chalk with flints 



Total 38 



In comparing this section with the one at Kirmington it should 

 be noted, (1) that no shells have been found in the laminated warp 

 at Limber ; (2) that the warp does not rest on glacial clays ; and 

 (3) that the base of the Limber warp is 92 feet above O.D., or 28 feet 

 higher than that of Kirmington. 



It would be premature to discuss the problems raised by these 

 interesting sections until the work of the Committee has been carried 

 further. For the present, therefore, we desire only to record the 

 data thus far obtained. 



The thanks of the Committee are due to Mr. W. H. Crofts and 

 Mr. G. W. B. Macturk for practical help in many ways ; also to the 

 Earl of Yarborough (landlord), E. P. Hankey, Esq. (agent), and the 

 occupiers of the brickyards — Mr. Hervey and Mr. John Housan — 

 for permission to put down the borings.
